I only have 159.15 on my pro-51 so I listen to them quite a bit. With Cottleville, as soon as the unit doesn't reply to a status check they call their cell phone. Lately, it seems like the dispatcher doesn't even try to ask a second time.
I've picked up as far as Warren County from the city. It's a nice place to be, yet at the same time it's bad. I don't know who to listen to. I have the options of St. Charles co, lsl/cottlevile, Wentzville, O'fallon is sketchy, STL County, STL City(includes FBI) & airport, the ISP and the municipalities on their system, the rest of the Metro East and a bunch of factories come alive at night.
